Abstract (en)

[origin: EP3611045A1] A relay (25) connects and disconnects an electrical circuit to which an inverter (16) and an electricity storage device (19) are connected. A BCU (22) controls the electricity storage device (19). An HC (27) controls an electric motor (15), the inverter (16) and the BCU (22). The HC (27) and the BCU (22) respectively have FET switches (30, 31) for controlling supply and stop of the excitation current in the relay (25). When the electricity storage device (19) is determined to be in an abnormal state, the BCU (22) transmits an abnormal signal to the HC (27), and when a predetermined time has elapsed, turns off (opens) the first FET switch (30) of the BCU (22). The HC (27) executes stop processing based upon the abnormal signal received from the BCU (22) and then turns off (opens) the second FET switch (31) of the HC (27).
